Verified Scalability Limits

The verified scalability limits provided in this guide are
validated by Cisco for supported platforms. If your scale
requirements exceed the verified limits, contact your Cisco
representative for further assistance.

Layer 2 Switching Verified Scalability Limits

For Layer 2 switching, the Nexus 34180YC supports:

4K MSTP, 4K RSTP in Generic Profile Mode
4K MSTP, 1K RSTP in L3 Heavy Profile Mode
507 RSTP and 4K MSTP in Generic Profile Mode
507 RSTP and 2K MSTP in L3 Heavy Profile Mode
MAC Address Table: 32K in Generic Profile Mode; 4K in L3 Heavy
Profile Mode

Layer 3 Switching Verified Scalability Limits

For Layer 3 switching, the Nexus 34180YC supports:

ARP IPv4 LPM: Maximum 32,768; Verified 32,000
IPv4 hosts: Maximum 4,096; Verified 4,000
Nhop ECMP: Maximum 17,408; Verified 15,500 (90% hash
collision)
Nhop ECMP: Maximum 65,536; Verified 55,700 (85% hash
collision)
Nhop ECMP: Maximum 256; Verified 255

Unicast Routing Verified Scalability Limits

The Unicast Routing verified scalability limits vary across
different Nexus models as specified in the table provided in the
user manual.

Frequently Asked Questions (FAQ)

Q: What should I do if my scale requirements exceed the

verified limits?

A: If your scale requirements exceed either the Verified
Topology or the Verified Maximum limit, please contact your Cisco
representative for further assistance.

Q: Are the verified limits applicable to all features and

platforms?

A: No, the verified limits are provided only for supported
platforms and features. If a feature is not supported for a
particular platform, the verified limit is not provided.

Cisco Nexus 3000 Series NX-OS Verified Scalability Guide, Release 9.3(8)
Introduction 2 Verified Scalability Limits 2 Verified Topology Limits 14

Revised: February 6, 2024,
Introduction
The values provided in this guide should not be interpreted as theoretical system limits for Cisco Nexus 3000 Series hardware or Cisco NX-OS software. These limits refer to values that have been validated by Cisco. They can increase over time as more testing and validation is done.
Verified Scalability Limits
The tables in this section list the Cisco verified scalability limits for Cisco NX-OS Release 9.3(8). These limits are validated with a unidimensional configuration. The values provided in these tables focus on the scalability of one particular feature at a time. Each number is the absolute maximum currently supported by this Cisco NX-OS release for the corresponding feature. If the hardware is capable of a higher scale, future software releases might increase this verified maximum limit. Results might differ from the values listed here when trying to achieve maximum scalability with multiple features enabled.

Note 1. Verified limits are provided only for supported platforms.
2. If a feature is not supported for a particular platform, the verified limit is not provided.
3. If the verified maximum values are exceeded in an ALPM or a non-ALPM mode, you get a table full syslog even in the hash collision scenario.
4. For Verified Maximum, 16 path ECMP is tested with 40K IPv4 and 40K IPv6.
5. If your scale requirements exceed either the Verified Topology or the Verified Maximum limit, please contact your Cisco representative. Based on your requirements, it may be possible to validate support for your requirement, as long as the scale capability of the hardware is not exceeded.

Verified Topology Limits
The tables in this section list the verified scaling capabilities with all listed features enabled at the same time. The scale numbers listed here exceed those used by most customers in their topologies. These numbers are not the maximum verified values if each feature is viewed in isolation.

Note

· The scale numbers in the Verified Topology Limits tables are for the Non- ALPM mode and the default IPv6 LPM carve

value is 256 for all the platforms.

· For the verified topology scale numbers for 3132Q platform, refer to the scale numbers for 3132Q-X platform since they are identical for both these platforms.

· All the scale numbers are with Unicast RPF disabled.
